Beauty products are designed to enhance how women look and feel, but emerging research suggests some may be doing far more beneath the surface. In this article, Dr Isioma Okolo examines the growing concerns around everyday cosmetic products, hormonal health and the long-term impact of repeated chemical exposure on women’s bodies.
On any given weekend in Nigeria, salons are full. Hair is relaxed, braided, coloured and styled. Skin is exfoliated, perfumed, lightened and polished. Beauty rituals are woven into everyday life. They are social, cultural and deeply personal.
But as a consultant obstetrician and gynaecologist, I have become increasingly concerned that some of the products women use routinely in the name of beauty may also be quietly shaping their health.
In the clinic, conversations about infertility, fibroids, miscarriages or menstrual problems usually focus on hormones, age, stress or genetics. Rarely do we discuss another possible contributor hiding in plain sight: the chemicals women are exposed to daily through cosmetics, hair products, fragrances and skin creams.
Yet a growing body of scientific evidence suggests these exposures may matter far more than many people realise.
Many personal care products contain substances known as hormone-disrupting chemicals. These compounds can interfere with the body’s hormonal systems. The World Health Organisation and the United Nations Environment Programme have both raised concerns about their effects on reproductive health.
Common examples include phthalates, parabens, preservatives that release formaldehyde, and certain heavy metals. These chemicals have been documented in hair relaxers, fragrances, cosmetics and skin products used globally, including many marketed specifically to Black women.
Hormones act as the body’s chemical messengers. Research increasingly suggests that endocrine disruptors may mimic or block natural hormones, potentially affecting ovulation, menstrual cycles, pregnancy and long-term reproductive health.
Studies have linked chronic exposure to conditions including fibroids, endometriosis, infertility, polycystic ovarian syndrome (PCOS), early puberty, miscarriage and certain hormone-sensitive cancers. Importantly, these effects do not usually appear overnight. Exposure accumulates gradually, often invisibly, over years
This conversation matters particularly in Nigeria, where beauty practices exist within powerful social and economic pressures. Across workplaces, schools, media and social spaces, women are often expected to present themselves in highly specific ways. Straightened hair, lighter skin and polished aesthetics are not simply personal preferences. They are often tied to perceptions of professionalism, femininity and social acceptance.
The skin-lightening industry alone remains widespread despite repeated health warnings. Informal beauty markets continue to sell unregulated creams, imported cosmetics and “mixing” products whose ingredients consumers may not fully understand. Some contain steroids, mercury and other potentially harmful substances. Even products labelled “organic” or “natural” are not always transparent about their contents.
Regulation exists, but enforcement is uneven. Nigeria’s National Agency for Food and Drug Administration and Control (NAFDAC) oversees cosmetic safety, yet counterfeit products, incomplete ingredient disclosure and poorly regulated informal markets remain persistent challenges.
This creates a troubling public health reality. Women are expected to make informed choices without always being given accessible or reliable information.
There is also a clear inequality issue. Safer products are often significantly more expensive. Women with fewer financial resources may have less access to products marketed as non-toxic or low chemical, shifting the burden of protection onto individuals rather than regulators and manufacturers.
As an obstetrician and gynaecologist, I increasingly ask women about environmental and cosmetic exposures alongside more traditional medical histories. These conversations rarely provide simple answers. A woman struggling with infertility cannot point to one hair treatment and identify it as the cause. Human biology is more complex than that.
But patterns emerge.
The woman with recurrent miscarriages who has spent years using heavily fragranced products daily. The patient with severe fibroids has never once been asked about environmental exposures. Young girls are introduced early to chemical-heavy beauty routines long before their hormonal systems are fully mature.
These experiences do not prove direct causation. But they raise important questions deserving far greater scientific, clinical and public attention than they currently receive.
This is not about blaming women or fuelling fear around beauty practices. Women should not carry the responsibility for navigating poorly regulated markets alone. Nor is this an argument against self-expression, culture or care rituals that hold genuine meaning and joy.
It is about widening the lens through which we understand women’s health.
Women’s bodies do not exist separately from the environments they move through every day, including salons, markets, homes and workplaces. What is applied repeatedly to the skin and scalp does not always remain on the surface. Some substances can enter the bloodstream, interact with hormones and accumulate over time.
Public health experts increasingly argue that environmental exposures should become a routine part of women’s healthcare, not a niche concern. Clinicians should feel confident discussing cosmetic and chemical exposures during reproductive, antenatal and menopausal care. Regulators should strengthen ingredient transparency, product surveillance and public education. Consumers deserve clearer information than marketing slogans and fine print.
Women should not need a chemistry degree to make safe choices about everyday beauty products.
Beauty is often framed as a matter of confidence, identity or self-expression. All of that can be true. But beauty is also biological. And if beauty standards carry biological consequences, then women deserve greater honesty, transparency and protection than they currently receive.
